The sinking of MS Estonia: Case Reopened Part VII

They cannot be switched off by the user. What part of this confuses you?


The Estonia's hydrostatic release systems worked, and the buoys did indeed bob to the surface. But they did not transmit, because they were manual buoys and were not switched on.

If they had been automatic types they would have switched on 2 seconds after getting wet in seawater and when no longer held off by the magnet in their storage case. The user has no control over that.
For heavens sake, EPIRB's on a ship are switched off when resting in dry dock (say for a two-week period), so yes, they CAN be turned off. Yes, all the Hammar spring does is release the buoy from its bracket. Everybody is clear about that.
 
A modern EPIRB can be programmed with the ships MMSI number, but as far as I know, older EPIRBs broadcast their own unique identifier that was preprogrammed. So the registration is paper-based - basically to connect the EPIRB identifier to the ship in the registers. The EPIRB doesn't know better, so it will always broadcast. And as we know, when the EPIRBs where found and turned on, the did indeed broadcast. So no need to try to make up something about "no signal to transmit" - that is not relevant.
Lehtola is clear the fault happened at the installation stage. So this is different from an inspection stage or a ship-in-distress stage.

No.

The magnet in the storage case keeps them inactive. The user has no way to switch them off. If they're out of their case and get wet, they activate.
 
Translation from another language is always tricky, especially technical jargon. Luckily, I am familiar with the language in question.
How about the Brandenburg report?

Being familiar with both languages in question is critical. However, the translator of a technical document must also know the technology, which you don't in this case.

Irrelevant, since we know the EPIRBs on the Estonia were the old, manual, type, which are off until turned on.

Rushed off my feet today but will do soon. Finnish is very simple: the jargon is either an anglicised/scientific word or it is very logical, as in English when one makes a noun out of a verb. English has about three varieties of the same word (derived from Old English/anglo-saxon, latin, French) and we find many scientific words are Greek origin (as in words ending in '-ized'). So many of the same scientific terms in English are quite similar in Finnish. 'Buoy' = 'poiju' bearing in mind 'p' is closer to 'b' (which doesn't exist in Finnish) in sound. This is because most technical jargon is modern.
 
I think that is a tacit admission that it was Vixen's own singular definition. I mean, why would anyone "familiar with the language in question" need to use a third party translation?
I doubt that explanation only because the translation really does not look like anything a native English speaker would write. I feel the reluctance to name the source of the translation must have some other reason.
 
I have a bookshelf of about 700 science and engineering books. Vixen seems to have a bookshelf full of conspiracy books.
I used to have hundreds of books before moving but still have many reference books: history (sub section local history), biography, literary fiction, the odd Graham Hancock but in general, very eclectic. I have never claimed to be an engineer so I am not sure what point is being made here. But I do have encyclopediae.

Please do. You've been peddling the Brandeburg report for years, including your alleged superiority at interpreting it. You whined all through the SwRI discussion that we should move on to Brandeburg and the third one. Now that you finally had your chance to shine forth your knowledge of the Brandeburg findings, you've wasted several pages on the well-trodden path of EPIRBs. All I'm asking you to do at this stage is interpret one paragraph in your own words.

This is because most technical jargon is modern.
Technical jargon is, above all, technical and requires knowledge of the technology in order to choose the appropriate word in English. You don't know how EPIRBs work, so we wonder why you consider yourself an authority on how best to translate a description of one from any language.
 
I have never claimed to be an engineer so I am not sure what point is being made here.
You pretend to sit in judgment over engineers and your other betters who sat on the JAIC and reported on the accident. The point being made, as usual, is that you appear to have made absolutely no effort to educate yourself in the fields of knowledge that pertain to your judgment. But you seem to have accumulated a lot of conspiracy stories that form your principal sources.

No. You are trying to tell everyone how the JAIC got it wrong. And you are doing so from a position of profound ignorance nourished by your evident choice of reading material, nearly all of it unchanged by recent activity.

Quit stalling and interpret the paragraph from the Brandeburg report. You could have done so in the time it took you to write another page of drivel on EPIRBs.

This was archived to a word doc in my folder in 2021, when I had a subscription to HS, which I didn't want to continue as I already had a subscription to another news outlet. So, when reverse translated t'other day, no big surprise Google had since amended it, as it does have a function whereby people can 'suggest a better translation' (no, it wasn't me).
Who was it who changed "armed" to what they considered "a more apt meaning"?

Oh, and nothing was "reverse translated"; in both cases it was a translation of the same original text into English. One by Google translate, one by an entity capable of producing mangled English such as "Estonian emergency buoys were a forgotten tuning".
 
There were two ship radio technicians whose job it was to regularly inspect the buoys. This inspection means opening the bracket door carefully, lifting the beacon to check a signal light comes on (battery check) and then switch the 'off' button before it transmits a distress signal proper. They then record it as checked in the radio logs, which was done a week before the accident. However, whilst this may have not been done but marked off on the log anyway, what Lehtola was referring to here was the reason for it not tuning was in the installation phase [=Asetusvaiheessa] or, as google puts it: 'set-up stage'.

This seems to indicate that the EPIRB's were never properly registered with the satellite via its coding - mandatory for both manual or auto - and thus, when they successfully released from their brackets to the water surface, there was no signal to transmit (some kind of call back). As you know, the EPIRB's were housed on the roof of the bridge's wings, so hard to see how they could be manually switched on even if technically off because of the failure at the installation phase. However, Lehtola was a lawyer so was probably reciting feedback given to him which lacks finer detail. The set-up stage refers not to the inspection and testing phase but to the first installation, which we can see in the word 'Asetus' = set up, to place, to install. This is a different word used from to tune or to arm.
There is nothing to tune.
The buoys are sealed units.

You take them out of the box and out them in the holder.

They are set to transmit on a fixed frequency at the factory, in a workshop.

When the buoys were recovered they were switched on and worked as they should, transmitting a distress on the correct channel.

Bridge Wings do not have a roof. They are open deck spaces on either side of the bridge.
EPIRB buoys are mounted on the outside of the bridge structure or a wing railing in a position where they can be easily reached.

You are posting the same bollocks as in every other post.

They cannot be transmitting signals when not immersed in four feet of water!
Yes they can, they have a switch for manual operation as well as the water activated switch.

Best practice is to activate manually and throw them away from the ship.

The buoys on Estonia had no water activated switch, they were manually activated only.
We know this because we know their make and model and they were recovered in an off condition.

But to come out of the bracket, the Hammar spring needs to release the wretched thing. It doesn't transmit signals until it bobs up to the surface! We don't want them transmitting signals all day long.

Absolute nonsense they cannot be switched off ever; they are switched off whilst in dry dock.
After they are activated by water a buoy will transmit until the battery is flat.

Buoys with just a manual switch can be turned on and off.

They are off if the manual switch is off and the water activated switch is dry, or as posted earlier if they are in their container.

They are only broadcasting if the manual switch is on or the water activated switch is wet.
